Monazite occurs as accessory minerals in igneous, metamorphic, and sedimentary rocks. In addition, monazite is found throughout the world in placer deposits, beach sands, and is also a component of the ores of the Bayan Obo deposit (Table 6 and Fig. 20 ). Monazite is a phosphate mineral containing approximately 70% REE oxides.
A number of primary ores such as phosphate rock, gold-, copper- and rare earth ores contain considerable amounts of accompanying uranium and other critical materials. Energy neutral mineral processing is the extraction of unconventional uranium during primary ore processing to use it, after enrichment and fuel production, to generate greenhouse gas lean energy in a nuclear reactor. Energy ...

Monazite mineral is primarily used as an ore for extracting rare earths particularly cerium and lanthanum. In the present study, the chemistry and distribution of monazite found in the beach sands of Neendakara-Kayamkulam belt in Kerala, south India, is studied using advanced techniques and standardized methods.
Rare earth elements are essential for modern life products and green technologies. Recent supply constraints have boosted the development of rare earth projects after the price peak of 2011. The feasibility of a project depends on the definition of a processing route, which in turn depends primarily on the rare earth mineral, with monazite and bastnaesite representing the two most relevant ...
Monazite ore should be ground to a fineness of 150 micrometres in a grinder. Monazite ore is composed of 55-60 per cent rare-earth metal oxides, 24-29 per cent P2O5, 5-10 per cent ThO2, and 0.2-0.4 per cent U3O8. At input temperatures of 150 to 180 °C, pulverised monazite is blended with strongly concentrated sulfuric acid (93 per cent acid).
